CHAIN-PUMP.

SPECIFICATION forming part of Letters Patent No. 431,284, dated uly 1, 1890.

Application filed February 28, 1890. Serial No. 342,040. (No model.)

To all whom it may concern.-

Be it known that I, BENEDICK RAU, a citizen of the United States, residing at Red Bud, in the county of Randolph and State of Illinois, have invented certain new and useful Improvements in Chain Pumps; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to chain-pumps.

The object of my invention is to construct a cheap and durable chain-pump; and to this end the nature of my invention consists of constructions and combinations, all as will be hereinafter set forth in the specification,

and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a vertical longitudinal section of my improved chain-pump; Fig. 2, a like section of the spout; Fig. 3,a side view of the receiver and tubing, and Fig. 4 the thimble.

A represents the case of the pump, having the usual cover B for the top; 0, the receiver, having its straight front face abutting against the front of the casing A, and provided With an opening 0 in said front face and a metal tubing 1) secured in its bottom, through which the Water is drawn; E, the spout provided with a flange (2, an interior screw-thread c, and an interior shoulder 6 for the purpose hereinafter described; F, the thimble, having a flange g and a screw-threaded end It. The case, cover, receiver, tubing, spent, and thiinble are preferably made of galvanized iron.

\V hen the pump is put up, as over a well, the receiver C, to which is secured the galvanized-iron tubing D, and the spout E are secured to the pump-case A by passing the screw-threaded end h of the thimble F through the opening 0 in the receiver 0, then through a suitable opening in the side of the case A, when the end of the thimble will project outside of the case. The spout E is then placed over the screw-threaded end hand the spout revolved until the flange g on the thimble is brought up against the inside of the receiver 0, the flange eon the spout brought up against the outside of the case A, and the screwthreaded end h of the thimble C abuts against the shoulder e in the interior of the spout, when the whole is secured together in position to receive the water that is elevated by buckets attached to an endless chain in the usual manner.

It Will be seen that by my construction the thiinble securely attaches all parts of the device together, and the usual fastening devices now employed for attaching the receiver and spent to the case of a chain-pump are entirely done away with, thus making a cheap chain-pump that can rapidly and inexpensively be placed in position for use.

I am aware that it is old to construct a receiver with lips cast thereon which project into or through the casing, and the spout, casing, and receiver secured together by means of bolts; also that it is old to connect faucets to the casing by means of thimbles; but my device differs from such constructions in that the straight front face of the receiver abuts against the casing, and instead of the usual lips being cast on the receiver and projected into or through the casing, and the spout, receiver, and easing being connected by bolts, a screw-threaded thimble is inserted through an opening in the receiver and a similar opening in the casing and screwed into the end of the spout, which secures the spout, receiver, and easing together Without any space between said receiver and casing. Theadvantages of this construction are that the formation or casting of the lip on the receiver and the space between the casing and receiver incident to the use of such lip, and leakage of water through said space to the casing-stand, are avoided, for the reason that in my case as the receiver has no lip it directly abuts against the casing, and no leakage of water can occur between the receiver and casing-stand, and, furthermore, all boltconnections between said parts are done away with.

Having described my invention, what I claim is In a chain-pump, the combination of the case, the receiver having its straight front face abutting against said casing, the spout having an interior screw-thread and shoui- In testimony whereof Iaflix mysignature in der, and the screw-threaded thimble passing presence of two Witnesses. through an opening in the receiver and easing and screwed into the end of said spout LENEDIICK for connecting the case, receiver, and spout Witnesses:
